DRAPERY-CURTAIN-POLE FIXTURE.

Specification of Letters Patent.

Patented May 4, 1920.

, Application filed November 13, 1918. Serial No. 262,346.

To all whom it may concern:

Be it known that I, WVALTER EDWARD Kr n- BER, a subject of the King of Great Britain, residing at 87 St. Augustines road,'Camden Square, London, N. V. 1, England, have invented Drapery Curtain Pole Fixtures, whereof the following is a specification.

This invention relates to that class of curtain rods or poles in which for the purpose of opening or closing the curtains the rings from which same are suspended are moved in one direction or the other along such rods or pole by a rotary movement imparted thereto, which causes the convolutions of a worm spirally wound around the rod to act against each of the rings and by its thrust impart a traversing movement thereto along such rod according to its direction of rotation, and it consists in the method of supporting and actuating such rods which 1s hereinafter described and claimed.

In the accompanying drawing.

Figure 1 represent a front elevation of one embodiment of this invention adapted for carrying a pair of curtains, the main operative band being omitted for, convenience of illustration.

Fig. 2 represents on a larger scale a side elevation of one end of said pole.

Fig. 3 represents a side elevation of the part shown in Fig. 2, the pole being in transverse section.

Fig. 4 represents on the larger scale a front elevation of one end of another embodiment of the invention in which the band contracting rollers are grooved.

Fig. 5 represents a side elevation of the embodiment shown in Fig. 1.

Fig. 6 represents another form of embodiment showing a front elevation of a window casing having two windows, each provided with a pair of curtains, both pairs being disposed on a single pole, which when rotated will cause each pair to close simultaneously in opposite directions.

The same reference numbers indicate corresponding parts'in the different figures.

In these drawings 1 is the pole'or rod on which a worm or rib 2 is formed or wound spirally so as to constitute a projection from the periphery thereof, and whlch bearing against the side of the rings 3 mounted thereon as such pole is rotated will by its thrust act in the manner of a conveyer and by propelling the rings along the rod draw the curtains to which same are attached in one direction or the other according to the direction of rotation. The weight of the curtains acting on the rings 3 will keep them down to the pole 1 to receive the thrust of the conveyer 2, but will permit of the necessary slip as the pole rotatesto prevent such a. pull being transmitted to the rings as would be liable to cause damage to the curtains when same have been opened out to the full extent.

The drapery curtain pole 1 is supported in pole hangers or brackets a. Thesebrackets have hook shaped supports each of which is provided in its lower bend with a pair of rollers 5 disposed in parallel relationwith each other and spaced apart a distance less than thediameter of the drapery pole to be supported thereon. The brackets are provided with downward openings or spaces between the peripheries of the rollers.

A flexible band 6 is looped over the plain end portions 8 of the drapery pole, engaging the upper periphery thereof andcontracted into contact with the lower periphery there of at the sides of the pole and passed in contact with the adjacent peripheries of the rollers 5 and depending between them through the openings in the brackets.

In the form shown in Figs. 4 and 5 where the rollers are grooved, the operative band is in the form of a cordwhich engages the grooves of the rollers.

The pole i'fdesired may be provided with an independent pulley 7 on which an auxiliary actuating cord 6 may be suspended for use 1n case of breakage or other emergency.

Each end of the rod 1 is provided with a space 8 free of the convolutions of the worm 2 for a sufiicient length to allow of the pole being cut to length to suit the particular window with which same is to be employed, while insuring the drawingback of'the curtain to the required extent, and on to which free space the outer rings 3 pass, and where they remain until picked up again by the worm 2- on the rotation of the rod or polein the reverse direction to that which effected the opening movement, the worm bearing against the opposite side of the upper edge of the ring 3 to that on which it had previously acted. V

The. action of the worm 2 being solely against the side of the rings- 3'which are perfectly free between the convolutions thereof, such the rod 1 by a purely thrust movement, and there will be no tendency of them to turn rings will be impelled along with the rod as it is rotated, and to carry the curtains to which they are attached with them, while when fully distended or withdrawn the thread or worm 2 will simply slip over the side of the ring on which it bears without transmitting any undue strain through said rings to the curtains.

The bracket or hanger 4 may be provided with a hook 10 to engage an eye 11 on the inner ring 3 so as to limit the distension of the curtain and to prevent its inner end being drawn away from that side of the window frame.

The ring '3 may if desired be covered with a soft material such as leather or the like, which will prevent all noise or rattle of the rings as they are impelled r thrust along the rod or pole.

, The rod or pole 1 might be provided wit a collar to determine or limit the inward movement of the extreme ring 3 of the curtains.

The space 8 left free of convolutions at each end of the rod or pole 1 is preferably such as to insure that the inner curtain ring 3 shall remain engaged with the end of the worm 2 when the curtain has been drawn fully back, so that when by the reversalof the rod 1 same is moved in the direction to distend the curtain it will after a certain travel draw the next ring 3 into position for the worm 2 to again engage it, and so on with each of the suceeding rings.

As applied to a rod carrying a pair of curtains which require to. be opened and closed from and to the center of the pole 1, as shown in Fig. 1 the pole is provided with a worm or thread 2 of right and left handed pitch respectively on theopposite sides of the center thereof so that the rotation of the worm will operate upon the rings 3 to move the two curtains simultaneously in opposite directions.

In Fig. 6 the rod or pole 1 is shown applied to a casement or frame having two windows each provided with a pair of ourtains 9, 9, and 9 9*, the separate curtains of which require to be opened and closed in opposite directions, andthe two pairs simultaneously operated by the rotation of the rod or pole 1.

For this purpose the said rod or pole 1 is on each side of the center of its length provided with two worms 2 of opposite pitch acting respectively on the rings 3 of the two sets of curtains 9, 9, and 9 9".

It will be readily understood that this application of a single pole or rod to a plurality ofwindows may be extended to three or more windows the curtains of which require to be simultaneously opened or closed in one operation by the rotation of such pole or rod.

The pole or rod may if necessary be supported intermediate its two extremities by an additional hanger or bracket 4 mounted at a point where two curtains of a pair are to meet or between the sets of curtains when a plurality of same are to be actuated by the same rod or pole. 7

What I claim as m invention, and desire to secure by Letters P atent, is

1. A drapery curtain pole fixture comprising pole brackets having'hook shaped supports each provided on its lower bend with a pair of parallel rollers spaced apart a distance less than the diameter of the pole to be supported, one of said brackets having a downward openingbetween said rollers, a drapery curtain pole adapted to be dropped into or lifted out of said hook shaped supports and provided with plain end portions engaging said rollers and a spiral rib between said end portions, drapery suspension rings hung on the spirally ribbed portion of said pole and movable lengthwise thereon by the action of said spiral rib on the rotation of said pole, and a flexible operative band looped over said pole, engaging the upper periphery thereof and adjacent peripheries of said rollers and depending between said rollers through said downward opening- 2. A drapery curtain pole fixture comprising pole brackets having hook shaped supports each provided on its'lower bend with a pair of parallel rollersspaced apart a distance less than the diameter of the pole to be supported, one of said brackets having a downward opening between said rollers, a drapery curtain pole adapted to be dropped into or lifted out of said hook shaped supports and provided with plain end portions engaging said rollers and a spiral rib between said end portions, drapery suspension rings hung on the spirally ribbed portion of said pole and movable lengthwise thereon by the action of said spiral rib on the rotation of said pole, and a flexible operative bandlooped over said pole, engaging the upper periphery thereof and adjacent peripheries of said rollers and depending between said rollers through said downward opening, said rollers being grooved and said band being in the form of a cord fitting said grooves. r

In testimony whereof I have signed'my name to this specification in the presence of two subscribin witnesses.
